| contents | The intensities of all rovibrational electric quadrupole absorption lines in $^{16}$O$_2$($X^{3}Σ^{-}_{g}$), for which the vibrational quantum number is $v \leq 35$ and the total angular momentum quantum number is $J \leq 40$, are calculated in the intermediate coupling using a new $\textit{ab initio}$ quadrupole moment curve of the ground electronic state of O$_2$. The calculated values agree with those available in the HITRAN database, which at present includes only the $1$-$0$ fundamental vibrational band of $^{16}$O$_2$($X^{3}Σ^{-}_{g}$). We therefore recommend using the intensities of the vibrational overtones and hot bands reported here in updating the HITRAN database for O$_2$ in the upcoming 2024 edition. |
